That would be the following:

"5.7.4 Line breaks without hyphen character

Allow the specification of a set of characters after which the
composition process may introduce a line break without inserting a
hyphen character. For example for '/' characters in URLs. "

I don't see how that (as written) would help in the programlisting case.
What I  want is the ability to specify a character that indicates the
line was broken for typographical reasons and I want that character to
appear at the end of the line so that all these characters are aligned,
just like in a professionally published book.

For all use cases, you would want the ability to tell the renderer to
stop processing if this happens. That way if Dick is preparing a
manuscript for print publishing and wants to break all the lines
manually, he can be sure he hasn't missed any.
